Driving economically ECO mode
ECO mode is a function that
optimises fuel consumption. It affects engine power and torque,
acceleration, gear shift indication,
heating, air conditioning and electrical consumers.
ActivationPress the ECO button. Control
indicator illuminates when activated
and a corresponding message
appears in the Driver Information
Centre 3 84.
During driving, it is possible to
temporarily disable ECO mode, e.g.
to increase engine performance, by
depressing the accelerator pedal
firmly.
ECO mode is reactivated when
pressure is reduced on the
accelerator pedal.
Deactivation
Press the ECO button again. Control
indicator extinguishes.
Control of the vehicle Never coast with engine not
running (except during
Autostop) Many systems will not function in this
situation (e.g. brake servo unit, power
steering). Driving in this manner is a
danger to yourself and others. All

Driving and operating111Idle speed control
To increase the idle speed press the
switch. After a few seconds the
function will be activated.
The function will be deactivated
when:
■ The clutch pedal is depressed
■ The accelerator pedal is depressed
■ MTA is not in N (neutral)
■ Vehicle speed is above 0 mph
■ Control indicator A, W or C
illuminate in the instrument cluster
To increase or decrease the fast idle
speed rate, consult a workshop.
Overrun cut-off
The fuel supply is automatically cut off
during overrun, i.e. when the vehicle
is driven with a gear engaged but accelerator is released.
Stop-start system The stop-start system helps to save
fuel and to reduce the exhaust
emission. When conditions allow, it
switches off the engine as soon as the
vehicle is at a low speed or at a
standstill, e.g. at a traffic light or in a
traffic jam. It starts the engine
automatically as soon as the clutch is
depressed. A vehicle battery sensor
ensures that an Autostop is only
performed if the vehicle battery is
sufficiently charged for a restart.
Activation
The stop-start system is available as
soon as the engine is started, the
vehicle starts-off and the conditions
as stated below in this section are
fulfilled.Deactivation
Deactivate the stop-start system
manually by pressing the stop-start
Î button. Deactivation is indicated
when the LED in the button
illuminates.

Driving and operating123To reduce the operating forces of
the parking brake, depress the
foot brake at the same time.
Control indicator R 3 81.
Parking 3 114.
Retractable parking brake
Depending on vehicle, the parking
brake lever retracts to the horizontal
position even with the parking brake
applied.
To release the parking brake, pull the
lever up slightly, press the release
button and return the lever to the
horizontal position.
To apply the parking brake, pull the
lever up and release it. The lever rests
in a horizontal position.
Brake assist
If the brake pedal is depressed
quickly and forcefully, maximum
brake force is automatically applied
(full braking).
Maintain steady pressure on the
brake pedal for as long as full braking
is required. Maximum brake force is
automatically reduced when the
brake pedal is released.
Brake assist is not available during an
Autostop. Stop-start system 3 111.
Hill start assist The system helps prevent unintendedmovement when driving away on
inclines.When releasing the foot brake after
stopping on an incline (with the
selector lever in a forward gear or
reverse gear), the brakes remain on
for a further 2 seconds. The brakes
release automatically as soon as the
vehicle begins to accelerate.Caution
The Hill start assist cannot
completely prevent vehicle
movement in all situations
(extremely steep gradients, etc.).
If necessary, depress the foot
brake to prevent the vehicle from
rolling forwards or backwards.
The Hill start assist is not active
during an Autostop. Stop-start system
3 111.

132Driving and operating
The camera is typically installed
under the number plate moulding with a display monitor fitted to the driver's
sun visor.
Functionality
The rear view camera system
enables the driver to view the rear of
the vehicle in the display monitor
whilst reversing.
The system can be activated or
deactivated by selecting the
Start/Stop button located on the right-
hand side of the display monitor.
The remaining buttons on the monitor enable the user to select source
AV1 or AV2 and adjust the brightness
and contrast of the display monitor.
To achieve the optimum visibility, the
rear view camera must not be
obscured by dirt, snow or ice.9 Warning
The system is intended as a
reversing aid and does not replace driver vision.
Do not let this feature tempt you
into take risks when reversing.
Failure to use proper care when
reversing may result in damage to
the vehicle, injury, or death.
Always check the outside,
rearview mirrors and glance over
your shoulder before reversing.
The driver assistance systems do not relieve the driver from full
responsibility for vehicle
operation.Fuel
Fuel for diesel enginesOnly use diesel fuel that complies
with EN 590. The fuel must have low
sulphur content (max. 10 ppm).
Equivalent standardised fuels with a
biodiesel (= FAME according to
EN14214) content of max. 7% by
volume (like DIN 51628 or equivalent
standards) may be used.
In countries outside the European
Union use Euro-Diesel fuel with a
sulphur concentration below 50 ppm.Caution
Use of fuel that does not comply to EN 590 or similar can lead to
engine powerloss, increased wear
or engine damage and may affect
your warranty.
Do not use marine diesel oils, heating
oils or entirely plant-based diesel
fuels, such as rape seed oil or bio
